Ratings and reviews

It seems the list of trusted roots may need updating? The app claims my Pixel 9 (stock OS, locked bootloader) uses an unknown root certificate.

Great tool, now I know 4 sure that TEE is completely broken on my device (due to using a custom ROM), damn you Samsung

Simple, works right after installation and open-source! Can only recommend.

What’s new

- Support saving the result to a file so that the result can be viewed from another device
- Some unimportant items are hidden by default; you can modify the options in the menu to show them again
